INJECTOR.

T 0 all whom it may concern Be it known that 1, JAMES H. C0011, acitizen of the United States, and a resident of Detroit, in thecounty ofWayne and State of Michigan, have invented certain I new and usefulImprovements in Injectors,

of which the following is a specification.

My invention relates-to the supply of fuel to internal combustionengines, and one of the main objects thereof is' to provide a devicewhich will distribute fuel-equally to all of the explosion chambers insuch en gines, either two-cycle or four-cycle, under' pressure; afurtherobject isto provide means for insuring aninitiaLminture to the'cylinders upon starting the engine; and a further object is to providesucha devlcewhich may be used for kerosene oil, gasolene, orotherdistillates, as fuel;

-My invention is fully described 1n the followingspecification, of whichthe accom- I panying drawings form a part, in which like referencecharacters are used to designate like parts 1n each of the views, and 1nwhich Figure 1 is a plan View of my injector,

similar to Fig. 4, but showing a modifica-- tion thereover.

In the drawings forming a part of this application I have shown a valvecasing mounted upon a gear ca'seB having a shaft 9 arrangedlongitudinally therein and provided with a cam 10 and a bevel pinion'llwithin the gear case and'with a sprocket 12 outside of said case,the camshown in the present instance belng one of four points;

, said-shaft is adapted to be rotated, through the sprocketj12, at thespeed of the engine shaft for two-cycle-engines, and atthespeed of theconventional cam-shaft for four cycleengines, the operativeconnectionswith said engine or cam shafts not being shown as theyaresubject to considerable modification for various makes of engines.

At 18-is showna seat for a conical valv 14.- having adownwardly extendedstem adapted to'be str-uck byarod 15 resting upon the cam-10 wherebysaid valve may be Specification of Letters Patent.

intermittently and vertically actuated inthe' revolution of saidcam, aspring l16 insurin'gthe seating of said valve when atrest; said"valve-is providedwith a groove 17in the side thereof, right hand asshown, of" a length approxlmating 1180 degrees of" a-circle, and with'apluralityof notches 18' in the upper edge thereof communicating, when;

the valve is'raised, with an air chamber'19 above; the valve and-apassage 20;interm ej diatethe height thereof in=the casing 7 The airchamber 19 is in direct communication-with a pipe 21 leading to-an aircompresser era-reservoir for air-underpressure, not shown, as either maybe employed and of any conventional form; the passage said valve,,bymeans ofan arm- 24; on-the' .70 of air to said chamber 19 is controlledby means ofa needle-valve 22 having a thread: 23 thereon, Fig.- 1,engaged with-the-valve casing in-such manner that the rotation of outerend. thereof and a push-rod'25, will j move said needle-valve 22 awayfrom and toward its seat, the degree of suchrotation determining theamount of air-under pressure admitted to the chamber 19, and it will benoted that this air in the chamber 19 assists in holding'the conicalvalve 1 1- on'its I seat.

Arranged diametrically opposite each;

otherand in the vertical, aXiaLplan'e ofthe valve 14 are two" oil po-rts26 and '27, Fig.

4-, controlled by needle-Valves 28-and 29, re-

spectively, each of'said needle-valves hav ing a spiral web or threadthereon engaged 7- .with the valve casing 7 and the'former of which hasan arm 30 connected therewith andwhich arm is in turn connected with thepush-rod 25-; communicating with the ports 26 and 27, whenthe-respective valves are unseated, are two oil supply pipes 31 and 32,respectively, only one of which is in operation as shown because of butone needle-valve, 28, being operatively connected with the push-rod 25,but I- may connect either; or both of said needle valveswith said rod',as desired, and thus admit oil from the corresponding pipes 31-and-32this duplicate arrangement of pipes allows me to .lead either-or both oftwo different oils to thevalve casing 7, according to conditions,

but the one operatively connected fuel pipe will suffice for thedescription of thein-' jector;

Vertically slidable on theshaft 9 is a plate or yoke 33 which isconnected, by means of a collar 34, with the end of the rod 15 and, bymeans of a collar 35, with a rod pressure for the oil with respect tothe air pressure. I may, however, as will be understood, change thisrelationship to meet varying conditions, either of the kind or characterof oil, or climatic, by varying the lengthsof the arms 24 and 30, eitheror both.

The passage '20 communicates with an angular bore 38in a washer 39 heldin place by means of a nut 40 and a screw '41, said bore communicatingwith a vertical bore 42 in. a rotary valve 43 having an outlet port 44inthe side thereof in communication with the vertical bore 42 and in thesame horizontal plane as four divergent ducts 45, 46, 47, and 48,leading to the respective tubes 49, 50, 51, and 52, in turn leading tothe respective. explosion chambers, not shown, and it will be seen thatthe rotary valve 43 acts as a distributer of the mixture to the enginecylinders.

Said rotary valve 43 is carried by a stem 53 having a bevel pinion 54 onthe lower end thereof enmeshed with the pinion 11 on the shaft 9 wherebycomplemental actuation of the conical valve 14 and the rotary valve 43results, and it will thus be seen that the mixture in the passage 20 isdistributed in equal degree to the different cylinders and in thedesired order, and the character of the mixture must be the same in allof the cylinders.

The modification shown in Fig. 6 consists in the provision of a ballcheck-valve 55 controlled by means of a spring 56 to prevent the airunder pressure from forcing the fuel vmit the air under pressure, andthus a very rich, initial, charge of mixture is assured.

It will thus be seen that I provide a substitute for the conventionalcarbureters which is adapted to oils or distillates, either or both;wherein a small quantity of oil is stored in the groove 17 of the valve14 to insure an initial charge which is very rich; wherein the mixturemay be enriched or impoverished at will by varying the pressure on theoil; wherein the delivery of the mixture is insured by means of airunder pressure; wherein a positive amount of mixture is delivered to thedistributer in each actuation of the valve 14 by means of the contactthereof with the cam 10; and wherein complemental-actuation of theintake valve 14 and the distributer is positively insured.

While I have shown a present preferred form of embodiment of the device,it will be obvious that I do not limit myself thereto, as many changesin the structure shown may be made to adapt my invention to varioustypes and makes of engines, without depart ing from the spirit of theinvention or sacri licing its advantages.

Having fully H described the invention, what I claim as new, and, desireto secure by Letters Patent, is

l. The combination with an internal combustion engine, of a plurality ofintak pipes, a valve casing provided with a mix ing chamber, means fordelivering air under pressure thereto, means for delivering oil undercontrolled pressure thereto to vary the character of the mixture, adistributer for delivering positive charges of mixture to said pipes,successively, a valve for con trolling the delivery of mixture to saiddistributer, a shaft, a cam thereon in operative connection with saidvalve, a pinion con nected with said distributer, a pinion enmeshedtherewith on said shaft, and means for rotating said shaft. I
